Hi Guys! John. The first time I got out of bed was in the hospital. You will get some PT there. Probably everyday twice a day. How ever it feels do it! It's going to hurt some whether you do one or 2 knees and I don't think doing 2 hurts double. You let your QUADS pull you up. And yes you might grit your teeth. So any quad strengthening you can do before surgery will only help. All those exercises they show you in PT and in the hospital strengthen & use the quads. I only had 6 weeks from 1st DR appointment to surgery, so even only a month of hard work at PT before surgerypays off. You may go to rehab before you go home. They wont let you go home if you can't get up. So if you need it rehab is good. Just know that every single day it easier to get up. In the beginning I had to think about it for a good 5 minutes before I would get up, now I just do it. I have this little deal with myself. I use a trigger phrase of "jennifer get up" and have decided that once I say that phrase, I'm getting up, NO MATTER WHAT. Ofcourse safety is a given. But I find half of this is mental. Yes it is also physically demanding. But still easier than what they were (knees) before surgery. Try and set up the house as much as possible, Strong chairs, no rugs, Raised toilet, shower chair, help with meals, easy clothes.
